Viewers pointed out that they "still kiss like 10-year-olds" and kept bickering throughout the filming - with even the Love Island narrator Iain Stirling making a number of jibes about their on-off romance.

Now Jani are fighting back against the rumours, and were last night spotted snogging at the Hammersmith Apollo where Dani was performing in her stage debut for Nativity! The Musical, alongside famous dad Danny Dyer.

An eyewitness said the pair seemed "very much in love" as they put on a passionate PDA in front of the cameras.

"They weren't aware they were being watched - they were snogging the pants off each other," said the source.

"It was a very tender moment between them."

The musical was the first time Dani has acted on stage.

In it, EastEnders star Danny plays Hollywood producer Mr Parker Lewis in the musical, and Dani portrays his daughter Polly - an aspiring actress whose dad will do anything to help catapult her to fame.
